OK, so I'm tired of my 40's carb starving when I'm making steep climbs. :rant: It's been a safety factor that keeps me from getting too steep ;), but it's conking out at too low of an angle. I already have off-road needles in the carb.

I'm thinking of making the leap to EFI. Anyone have recommendations as to
1) type (tuned port vs. throttle body)
2) type of intake manifold
3) manufacturer
4) etc.?

The engine is a 350 GM crate engine--circa 1985 design. It's the plain jane, low-end one--I didn't want too many horses under the hood. :rolleyes:

I've been told to get an EFI setup from a salvage yard. If so, anyone know which vehicle to look for?

I'm just now getting into this EFI thing, so I don't know alot about it yet. I know that you guys have the answers, though.

Thanks

I did this exact same thing with my carb'd 350. Mine had an RV cam but basically your stock 4bolt main.

GO GM TBI...parts EVERYWHERE!

I got the GM fuel injection setup off of a 90 Caprice Cop car. I took everything I could. Manifold, TB, injectors, full wire harness, distributor, all sensors, ECU

I got all the info from www.binderbulletin.org they are down today...
there is a fuel injection forum with a FAQ and everything u need to know.

It wasn't hard at all. You'll need a new fuel pump. external for TBI. I used a Master 2182 from autozone. You'll need a return line into your tank.

You'll need a VSS, vecicle speed sensor as it won't run 100% right without it.


It ran great. I got rid of the taurus fan as it messed with my electronics. Switched to clutched fan and it worked great!.

It moved that cruiser along awesomely with 4.10's and 37's. Started instantly and ran very smooth.

I can vouch for that tbi. When I did wrench, those things were pretty bulletproof. electronic carbs really. you should be able to pull everything you need from a suburban or the like from scrap... I replaced a few injectors on those, but that was relatively low maintenance. That set up is really just an electronic carb. Oh, and the phenolic spacer does wonders as well as the rv cam....
